Electric Axle Actuator

For efficient gear shifting

Schaeffler has introduced two solutions for internal combustion engine, hybridized and electrified powertrains: a highly integrated electromechanical actuator for multi-speed electric axles and an integrated parking lock actuator. Energy efficiency plays a decisive role in the development of hybrid and electric vehicles, but how can all the components in the powertrain utilize their full potential in terms of energy? Schaeffler is providing the answers to this question with its new actuator solutions, including an actuator for multi-speed electric axles (EAA) and an integrated parking lock actuator (PLA).

Transmission actuators for electric vehicles

Schaeffler’s electric axle actuator (EAA) will go into volume production this year and is an example of how transmission actuators are used in hybrid and electric vehicles. The EAA is based on the proven active interlock transmission actuator with integrated interlocking but operates without a selector axis. The key feature: the two adjustment motors are controlled only when gears must be engaged or disengaged.

Except for a minimal idling current, this actuator has almost zero energy losses. As an expert system partner, Schaeffler not only provides the hardware but also develops the software to ensure optimum performance in the entire system.
